Abstract
Provided is a Pt—Ru based quaternary metal anode catalyst for a direct methanol fuel cell (DMFC). The Pt—Ru based quaternary metal anode catalyst has high activity to methanol oxidation and strong resistance to catalyst poisoning due to carbon monoxide (CO), which is a byproduct of the methanol oxidation. Therefore, the Pt—Ru based quaternary metal anode catalyst can give high power density and can replace existing commercial catalysts.
